Description

The MICROSMD050F-2 is a surface-mount fuse designed for overcurrent protection in compact electronic devices. Key features include:
- Current Rating: 500 mA (0.5A)
- Voltage Rating: 32V DC
- Fast-Acting: Quickly interrupts excessive current to protect circuits.
- Compact Size: Ultra-small form factor (e.g., 0402 or similar) for high-density PCBs.
- Agency Approvals: Typically meets UL/CSA/IEC standards.
Commonly used in portable electronics, IoT devices, and automotive systems, it ensures reliable protection in space-constrained applications. Its low resistance and high durability make it ideal for sensitive circuits.
For detailed specs, refer to the manufacturer’s datasheet.

Equivalent

The MICROSMD050F-2 is a surface-mount fuse. Equivalent alternatives include:
- Littelfuse 0501.050 (500mA, 50V)
- Bourns MF-MSMF050 (500mA, 50V)
- TE Connectivity 0ZCM0050FF2E (500mA, 50V)
- Eaton MF-NSMF050 (500mA, 50V)
These are SMD fuses with similar ratings (500mA, 50V) and package sizes (0402/1005 metric). Verify specs for exact compatibility.

Features

The MICROSMD050F-2 is a surface-mount resettable fuse (PPTC) with these key features:
- Current Rating: 500mA (0.5A) hold current.
- Voltage Rating: 30V DC max.
- Compact Size: 0805 footprint (2.0 × 1.25mm).
- Trip Current: 1A (typical).
- Fast Response: Quickly resets after fault removal.
- Operating Temp: -40°C to +85°C.
- Low Resistance: <0.25Ω typical.
Ideal for overcurrent protection in compact electronics like portable devices, IoT, and PCBs.

Pinout

The MICROSMD050F-2 is a surface-mount fuse from Littelfuse, designed for overcurrent protection in compact electronics.
- Pin Count: 2 (standard SMD design with two terminals).
- Function: Acts as a fast-acting fuse (rated for 50V and currents up to 2A, depending on the variant). It protects circuits by breaking the connection during overcurrent or short-circuit conditions.
Key features include a small footprint (e.g., 0603 or similar size) and low resistance, making it suitable for high-density PCBs.
For exact specifications (e.g., current rating, package size), refer to the datasheet for your specific model variant.
